Idle City Sim 2051 is a free html5 game.
It works on both desktop/laptop and mobile.
It was made using the open source tabageos; Tad's Basic Game Objects, html5/javascript library.
You can play it here; https://tadgames.itch.io/idlecitysim2051
Game play is generally click/touch based, and idleness is achieved after all stats are in the green.
One difference with this game is that you can dig for basic minerals,
and so having the basic supplies is always possible by digging in empty spots for them.
I would love any feedback
